した時を想定して説明する。There is no vacant line that satisfies the above conditions, but the operation when the free line capacity of the entire transmission line is greater than the transmission speed of the calling subscriber terminal is shown in Figure 3. The following explanation assumes that a subscriber terminal (3b) having a transmission speed twice that of the above transmission speed makes a call.
加入者端末(3b)の発信を受けた交換機(1)は、空
き回1R(5a)と(5C)及び(6a)と(6C)を
集めるために。The exchange (1) that received the call from the subscriber terminal (3b) collects the idle calls 1R (5a) and (5C) and (6a) and (6C).
使用中の回M (5b)と空き回a (5a)、及び(
6b)と(6a)の切替え要求信号を、交換機(2)に

待つ。The time division switch is set so that the communication data being transmitted to line a (5b), which is in use at the same time, is also broadcasted to the idle line (5a), and waits for a switching response signal from the exchange (2).
この時の回線状態を第4図1こ示す。The line state at this time is shown in FIG.

対して切替え応答信号を送信し。The missing number is the exchange that received the above switching request signal (2)
transfers the communication data being transmitted from the currently used line R (6b) to the designated free line (6a), which is requested to be switched.
Also set the time division switch to broadcast broadcast times! For subscriber terminals that were using line (5b), a time division switch is set to transmit communication data from idle line (5a). Thereafter, it transmits a switching response signal to exchange (1).

。Yoshiko Zara, the exchange that received the above switching response signal (1
), times! For subscriber terminal 1 that was using (6b), set the time division switch to receive communication data from idle line 11A (6a), and set the time division switch to receive communication data from idle line 11A (6a).
The time division switch is set so that the broadcast transmission to 5a) and 5b is transmitted only once through line (5a). Thereafter, a switching completion signal is sent to the exchange (2), and the switching process is completed. The line status at this time is shown in FIG.
最後に、上記の切替え完了信号を受信した交換機(2)

, (6c) is obtained, and it is possible to set up a line at the subscriber terminal (3b) having a transmission rate twice the basic transmission rate.
ととも蔭こ、切替え過程では新旧双方の回線に通信デー
タを同報することにより、通信中の回線が中断すること
がないという効果がある。Besides, in the switching process, communication data is broadcast to both the old and new lines, which has the effect that the line in use will not be interrupted.
また、空き回Imを集めるのに複数の回線の切替えが必
要な場合には、上記の過程を複数回繰返せばよい。Furthermore, if it is necessary to switch a plurality of lines to collect the idle times Im, the above process may be repeated multiple times.
